Question

A body was moved covering 12m/s and after 6second it changes to 36 m/second finding out accelerate

Answer 1

Explanation:

Given-

v= 36m/s

u= 12m/s

t= 6 sec

a=?

From 1st equation of motion

v= u+ at

by putting the above values

36=12+ 6a

36-12= 6a

24= 6a

a= 24/6

a= 4

Hence acceleration is 4m/s2
